The invention relates to a design method of a standardized ocean platform block structure based on nodes, which comprises the following steps: extracting key nodes according to a standardized platform, the key nodes being a plurality of typical block nodes, and forming a standard block node library; according to the overall arrangement scheme of the chunks and the equipment weight, selecting and determining standard chunk nodes suitable for oilfield development from a standard chunk node library; prefabricating the selected standard block nodes, and carrying out stress and fatigue analysis; according to prefabricated standard block nodes, the sizes of a block stand column pipe, an I-shaped main beam and a block diagonal bracing pipe of the platform block structure are determined; determining the size of a secondary beam according to the deck unit area load; establishing an upper deck model and a lower deck model of the platform block structure according to the prefabricated standard block nodes, the I-shaped main beams, the secondary beams and the deck; and arranging a block column pipe, an upper deck model, a lower deck model and a block diagonal bracing pipe structure of the platform block structure to establish an overall model of the block structure.
本发明涉及一种以节点为基础的标准化海洋平台组块结构的设计方法,包括如下步骤:根据标准化平台提取出关键节点,所述关键节点为若干个典型组块节点,形成标准组块节点库;根据组块总体布置方案和设备重量,从标准组块节点库里选取确定适应油田开发的标准组块节点;对所选择的标准组块节点进行预制,并进行应力和疲劳分析;根据预制的标准组块节点,确定平台组块结构的组块立柱管、工字型主梁和组块斜撑管的尺寸;根据甲板单位面积荷载确定次梁尺寸;根据预制的标准组块节点、工字型主梁、次梁和甲板建立平台组块结构的上甲板模型和下甲板模型;布置平台组块结构的组块立柱管、上甲板模型、下甲板模型和组块斜撑管结构建立组块结构整体模型。
